Small pool, Chlorine level is driving me nuts.

[Greenfrog]

Thanks for the tips. I did mean NaPersulfate, not Monopersulfate. I thought they were the same thing.
I also thought that i needed some level of stabelizer (cya) in the pool. But you feel that zero is ok for a small indoor pool?
How do i lower the CYA level? or will it go away on its own if a stop adding any more?
My Lamotte tester is a Photometer, uses test tubes inserted into the machine, so I think its accurate. (was expensive!)
I will study your best guess link and let you know if I have any more questions.

Also, should i be using nonstablized Chlorine? or stick with my Calcium Hypochlorite granules? (I dont know if my granules are stablized or not)
What is the best way to get nonstabilized Chlorine? Is that just plain Walmart Bleach?
